RAIL-BLOCK CLAMP.

SPECIFICATION forming part of Letters Patent No.'698,31 4, dated April22, 1902.

Application filed August 21, 1901. Serial No. 72,809. (No model.)

vented a new and useful Rail-Block Clamp,-

of which the following is a specification.

This invention is an improved device for securing a block between switchand guard rails and frogs. Heretoforeit has not been customary to placefilling-blocks between adjacent rails; but owing to numerous accidents'it has become necessary to fill the space between such rails, andforthispurpose filling-blocks have been employed; and the ob-" ject ofthis invention is to provide a fillingblock, together with means forquickly and easily connecting it to the rail; and with this object inview the invention consists, essentially, of a' block shaped to fitbetween the head andbase of the rail and rest against the web of saidrail, andan angular plate adapted to clamp the block and extend beneaththe base of rail, said plate havingmeans for clamping it to the base ofthe rail upon the side opposite the filling-block.

The invention consists also in certain details of construction andnovelties of combination, all of which will be fully describedhereinafter and pointed out in the claims.

In the drawings forming part of this specification, Figure l is aperspective view illustrating the practical application of ourinvention. Fig. 2 is a sectional view, partly in elevation.

-5 are detail perspective views illustrating the clamp in detail.

Referring to the drawings, A indicates the rail, and B thefilling-block, which is shaped to fit against the web of the railbeneath the head of the rail and rest upon the'fiange, the outer orinclined face of the block extending from the outer edge of'baseto theouter edge of the'head of rail. The clamp forsecuring this filling-blockconsists of an angular bar or plate 0, the base 0 being adapted toextend beneath the base of rail and project a short distance beyond theedge of rail, said Fig. 3 is a detail view showing a. portion of thefilling-block, and Figs. 4 and projecting end having an oblong shapedopening 0 The arm O is arranged at an oblique angle to the .part 0' andis adapted to bind against the filling-block B, and the upper end of thearm 0 is provided with inwardly-proj ectin g teeth 0 which are intendedto'press into the wooden filling-block.

The member D is essentially in the form of a thick plate having athreaded aperture D atone end and a dependinglug D at the opposite end,said lug having a sizeand shape to pass through the opening 0 in the endof the plate or bar 0, and the lug has ashoulder D which is adapted tofit beneath the edge of the opening, as most clearly shown in Fig. 2.

A bolt E is screwed in the threaded aperture D, the end of said boltbearing in the angle between its base and web of rail, and a lock or jamnut E is interposed between the member D and the head of bolt for thepurpose of locking the bolt after adjustment.

lnjoperation the angular clamp-plate or bar .0 is arranged to bind thefilling-block B, and

the member D is then fitted and secured. The filling-block is thussecurely clamped to the rail, filling up the space at one side, and thuspreventing .the foot being caught between the headsof adjacentrails.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is v 1. The combinationwith-a-r'ail, of a block adapted to rest against the webthereof betweenthe head' and flange and an angular clamp-plate adapted to embrace saidblock and base ot'qthe rail, and aplate attached to the projectingend ofsaid angular clamp-plate having a bolt passing therethrough to bear uponthe rail, substantially as shown and described.

2. The combination with 'a rail, of a block adapted to fit against theweb of said rail between the head and base, an angulariclamping-plateadapted to embrace the said block and base of the rail and projectbeyond said base, a plate having its end projected through theprojecting end of the clamping-plate, the opposite end of said platehaving an aperture;

a bolt adapted to pass through said aperture,

and the nut arranged upon the bolt between the other end, and a bolt andlock nut all arthe plate and head of bolt, substantially as rangedsnbstantiallyas shown and described. IO

shown and described.

3. The combination with an angular clamping plate or bar, one end havingteeth, the I J other end having a rectangular-shaped open- \Vitnesses:ing, of a clamp member, having a threaded FRED T. RUDDOCK,

aperture at one end and a shouldered lug at SAMUEL O. LAMB.
